Abstract

L'invention porte sur des systèmes et dispositifs de détection comportant une électrode de détection (en particulier sélectrice d'ions ou redox) et une électrode de référence l'une ou toutes deux étant recouvertes d'une barrière perméable touchant l'échantillon à examiner de manière à ce que le principal contact entre les électrodes lorsqu'on constitue un circuit de mesure ne passe pas par l'échantillon. La barrière perméable renferme une zone de liquide (par exemple d'électrolyte) au niveau des électrodes et commande en le restreignant le passage dans les deux sens des analytes et impuretés à travers la barrière. La fonction principale de la barrière perméable est de ralentir la diffusion de l'analyte. L'identification du contenu d'analyte peut être plus rapide si l'on charge la zone liquide en analyte ou impureté pour réguler la diffusion. La méthode de loin préférée de détection de l'analyte se base sur des mesures du taux de variation du potentiel alors que l'analyte diffuse à travers la barrière.
